Item 1.01. Entry into a Material Definitive Agreement.

On June 15, 2010, Soligenix, Inc. (the “Company”) entered into a Securities Purchase Agreement (the “Purchase Agreement”), totaling $5,754,877 with accredited investors (the “Investors”), including members of the Company’s Board of Directors and its North American commercialization partner Sigma-Tau Pharmaceuticals, Inc. ("Sigma-Tau"), its largest stockholder.  Pursuant to the Purchase Agreement, on June 18, 2010, the Company completed the private placement to the Investors of 28,072,620 shares of the Company’s common stock and warrants to purchase up to 16,843,571 shares of the Company’s common stock.  The warrants are exercisable at a price of $0.28 per share for a period of five years commencing on June 18, 2010.  The expiration date of the warrants is subject to acceleration if the closing sales price of the Company’s common stock attains certain per share values.  Sigma-Tau invested $1,764,759 in this offering. Excluding investment proceeds from Sigma-Tau and certain other Investors, the Company will pay an aggregate placement agent/finder's fee to three different entities for up to five percent of the balance of the offering proceeds. The securities were offered and sold to accredited investors pursuant to an exemption from registration under Section 4(2) of the Securities Act of 1933 and Rule 506 of Regulation D promulgated thereunder.

The net proceeds from the sale of the Company’s shares of common stock and warrants will be used for working capital and general corporate purposes.

The Company also entered into a Registration Rights Agreement dated June 15, 2010 with the Investors, pursuant to which the Company has agreed to register with the Securities and Exchange Commission the resale of the shares issued in the private placement and the shares of common stock issuable upon exercise of warrants.

The foregoing description of the Purchase Agreement and the Registration Rights Agreement (collectively, the “Agreements”) and the form of warrant does not purport to be complete and is qualified in its entirety by reference to each of the Agreements and the form of warrant attached hereto as Exhibits 10.1, 10.2, and 10.3 and incorporated herein by reference.

The Agreements are provided to give investors information regarding the Agreements’ respective terms.  They are not provided to give investors factual information about the Company or any other parties thereto.  In addition, the representations, warranties and covenants contained in the Agreements were made only for purposes of those Agreements and as of specific dates, were solely for the benefit of the parties to those Agreements, and may be subject to limitations agreed by the contracting parties, including being qualified by disclosures exchanged between the parties in connection with the execution of the Agreements.  The representations and warranties may have been made for the purposes of allocating contractual risk between the parties of the Agreements instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors.  Persons reviewing the Agreements are not third-party beneficiaries under the Agreements and should not view the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or conditions of the Company.

Item 3.02. Unregistered Sales of Equity Securities.

The information contained in Item 1.01 is incorporated herein by reference.

The Company’s private sale of securities to the Investors described in Item 1.01 was made in reliance upon an exemption from registration pursuant to Section 4(2) of the Securities Act of 1933, as amended (the “Act”), and Rule 506 promulgated thereunder.  The Company’s reliance on the exemption was based, in part, on the Investors’ representations that each of them is an “accredited investor” as defined in Rule 501(a) under the Act.

Item 9.01. Financial Statements and Exhibits.
